/*
 * Project: Twitter Bootstrap Hover Dropdown
 * Author: Cameron Spear
 * Contributors: Mattia Larentis
 *
 * Dependencies?: Twitter Bootstrap's Dropdown plugin
 *
 * A simple plugin to enable twitter bootstrap dropdowns to active on hover and provide a nice user experience.
 *
 * No license, do what you want. I'd love credit or a shoutout, though.
